CHILD'S TYPEWRITING MACHINE.

Application filed larch 16, 1928, Serial No. 95,003, and in Germany larch 81, 1925.

My invention relates to childrens typewritmg machines of the type which are provided with a standard keyboard, type-bars, a. movable carria e and a laten mounted in said carriage. S uch mac lines while cheap of manufacture yet are strong and durable combined wit-h lightness of weight and will withstand the more or less rough usage to which they are likely to be put. The 0 ject of the present invention is to still further simplify the construction of such machlnes and to thereby reduce their cost of manufacture. To this end, I mount the paperguide preferably made of sheet-metal and adapted to cooperate with the platen on' the same shaft, on which also the holder for the platen is mounted, the said shaft moreover serving as a seat for the sprin s bearing against the paper uide for hol ing the latter in contact with t e platen.

Other features of my invention will appear from the following detailed description with reference to the appended drawings, in which I have shown an embodiment of my invention, by way of illustration, and in which Fig. 1 is a top lan view, partly in section, of so much of the typewriting machine as is necessary to illustrate the features of the present invention, Fig. 2 a

lorigitudinal section along line 2-2 in Fig.

1, ig. 3 a transverse section along line 3--3 in Fig. 1, Fig. 4 a cross-section along line 4-4 in Fig. 1, and Fig. 5 a similar section along line 5-5 in Fig. 1.

The machine, as shown in Fig. 2, is supported on a hollow base 1 made of sheet metal to which the machine is firmly secured by screws or otherwise (not shown). The frame of the machine comprises the longitudinal side walls 2, 3, a transverse rear wall 4, and a to -wall 5. The side walls, 2, 3 are forward y extended as shown at 6 in Fig. 1 to form a fence around the keyboard the keys of which are indicated at 7 in 1g. 2. "8 is a transverse support provided at its ends with the forwardly extending side members '9, 10. On support 8 rests the slotted arcuate member 11 actin as a ide for the type-bars, one of whie is in leated in Fig. 2 at 12. Transver'sely I across the top 5 is arranged an arcuate rest 13 (Fig. 2) for the vtape-bars when in inoperative position. 1th each typebar-m 1s pivotally connectedone of the eye 7 of the keyboard so that when a key is depressed, the corresponding type-bar swings rearwardly, i. e. toward the right in Fig. 2, striking the platen 14.

I The laten is supported in a carriage general y indicated at 15, which carriage travels transversely across the rear wall 4 of the machine being' supported by antifriction bearings 16 in guideways 17 secured to the transverse rear wall 4. On the carriage 15 is provided a rack 18, whereby the stepwise movement of the carriage is controlled. A pawl mechanism generally indicated at'19 in Fig. 1 cooperates with the rack 18 of the carnage 15, the said pawl mechanism projecting throu h an opening 20in the transverse rear wall 4. The construction of the pawl mechanism and its relation to the rack 18 on the carriage 15 are such that every time a cross-piece indicated at 21 in Fig. 1 has been depressed and rises again, the carria e is advanced one tooth of the rack in the direction toward the left in Fig. 1, the carriage being under the pull of a spring mechanism indicated at 22 in Fig. 1 and described more in detail further down. i

As shown more partieularli'l in Figs. 2

and 4, the carriage 15 for platen 14 comprises a 1011 'tudinal flat part 23 provided with. gui e rails 24, 25 preferably made integral with part 23. To the latter is secured a U-sha ed yoke 26, in the arms of which is rotata ly 1ournalled a shaft 27 on which is mounted the holder 28 for the platen 14. On shaft 27 is' also mounted the.

paper-guide 29 by means of eyes 30 31 (Fi 3). The paper pre erably made of light sheet-metal is caused to bear against the platen 14 by light sprin 32, 33 encircling shaft 27' and bearing with their free ends against the paper-guide 29. The other ends of the. sprin 32, 33

as through holes 34, 35 in the older 28 I or the platen.

The aper-guide 29 is rovided with spaced lugs 36 (Fig.3) in w ich are loosely r rollers 37 ads ted to inst the paper on platen 14 t rubthrough suitable openmounted small rub hear her ro erlsl projecting d 29 Smu i int e a r-gui e spacing tiibzs 38, 39 81 provided between the e es 30, 31 and the side members of the hol er for the platen to prevent any lateral displacement of the paper-guide relative to the platen 14.

ide 29, which is '27, the holder is of the .said hol or an For rocking the holder 28 about the shaft provided with a depending flange 40 adapted to be engaged by the rear end of the shift-key device. In Fig. 1 are shown two shift keys 41, 42, the levers 43, 44 of which are united to one arm 45, which at its rear end carries a roller 46 adapted to bear against the depending flange 40, of the holder 28. A transverse rod 47 holds the levers 43, 44 of the two shift keys 41, 42 firmly together thus roducing a rigid structure. One of the sid e members of holder 28 is provided with two lugs 48, 49, and similar lugs 50, 51 are provided ontheone sidewall of the carriage. In the lugs 50, 51 are seated set-screws 52, 53, and by these setscrews the rocking movement of the holder 28 is limited, whenever'one of the shift keys 41 or 42 is depressed.

The pa er-guide 29- is provided with a tubular e ge which as shown in Fig. 1 is divided into five portions 54, 55, 56, 57 and 58. The portions .54 and 58 act as'bearings for a paper clamp 59 (Figs. 1 and 4), which is held against the platen 14 by a light spring 60. The portions 55 and 57 of the tubular edge serve as bearings for a paperrest 61 made of apiece of bent wire. The central portion 56 actsias-a reinforcement paper-guide 29. The ends of the wire paper-rest 61 are offset as shown at 62, 63 m Fig. 1 to form abutments for maintaining the paper-rest in operative position.

A spring 76 shown in Fig. 4, which spring is attache to the carriage and the movable holder 28 acts to return the latter to its normal position each timeit has been rocked by the depression of a shift key.

I claim as my invention:
